Each of this pair of woodcuts is marked out with a flap at the right side on which are printed instructions for folding and glueing the sheet into a rectangular column. They are printed in green and each has lettering down one face of what would be the column if so fixed. The idea is related to Finlay's installation at the Kroller-Muller Museum, near Arnhem, where he put stone column bases on actual trees. Finlay believes that this - or something like it - may have been done by the Romans.
